%N Triangle read by rows: replace A003983(n,k) with F(n).
%F Replace term A003983(n,k) with F(n).
%F Triangle T(n,k)=sum{j=0..n, [j<=k]*[j<=n-k]*(F(j+1)-F(j))}. [From _Paul Barry_, Jan 18 2009]
%e First few rows of A003983 are [1; 1,1; 1,2,1; 1,2,2,1;...] which become [F(1); F(1),F(1); F(1),F(2),F(1); F(1),F(2),F(2),F(1);...] =
